An island made entirely of tin sheets. In the center of the island, there is a research institute (ostensibly a Platinum Hotel), where the Marquis of Garian transformed his villa to deceive the robot army. It is actually a huge spaceship. The operation, management and control of the island are all the responsibility of robot Platinum.

Platinum Hotel

All hotels are made of tin. But its services, facilities and surrounding environment are very high. It's actually the villa of Duke Garian Brechin. In the basement, there is a Duke Garian Birkin maze of 184 km, and no one can go out. The central hall of the maze contains the secret plans of Duke Garian Brechin. At first, Nobita and others used robot mice to move forward. Doraemon woke up and finally found the central hall with the secret prop "maze exploration ball" The control device of Baijin Island is also in the hotel, with automatic control function. To attract people, TV stations are used to broadcast advertisements in the middle of the night.

Gamoga star

A very beautiful planet with a developed robot civilization. But under the rule of robots. In the original book, it is the Japanese language of the earth. The culture is similar to that of the earth (especially Japan), and the clothing is similar to that of Europe and America. Robots similar to Santa Claus on earth also exist in the Arctic. The inhabitants of this planet don't like the gentle character of quarrelling, but they are too weak to walk because they are too eager for an easy life result.
